Abstract

An embodiment provides a belt stall protection device. The belt stall protection device comprises a power supply module, a detection module, a verification module, a protection module, an alarm module and a time delay module, wherein a power supply is electrically connected with the detection module and the time delay module, and the verification module is in communication connection with the detection module, the protection module, the alarm module and the time delay module. When time for rolling of a driven roller of a belt conveyor by a circle is abnormal and the verification module does not receive a signal of the detection module within a set time, the verification module sends a signal to the protection module and the alarm module, the protection module enables a motor of the belt conveyor and the belt conveyor to stop running, and the alarm module gives out sound and light to remind workers of a fault; after the belt stall is relieved, a reset button is pressed down, the protection module does not act, the normally closed point of the time delay module shields the detection module and allows the detection module not to work, and after the belt conveyor is normally started for 5 seconds, the relay of the time delay module is closed, shielding of the detection module is stopped, and the detection module works, somisoperation of the protection module when the belt conveyor is not normally started can be avoided.

Description

technical field [0001] The present application relates to the field of belt stall, in particular to a belt stall protection device. Background technique [0002] In the process of belt transportation, the fault caused by the motor of the belt conveyor being cut off from the wheel pin, the belt load of the belt conveyor is too heavy and the tensioning device of the belt conveyor fails is called belt stall. The stall of the belt is manifested as the motor of the belt conveyor running The belt of the belt conveyor is not running and the motor of the belt conveyor and the main roller of the belt conveyor are running and the belt of the belt conveyor is not running. The stall of the belt will cause the material to press the belt and the belt will be broken, which will cause the belt conveyor to not work normally and affect the belt conveyor. transport efficiency. [0003] In order to prevent the material from being pressed by the belt and the belt to be broken due to the belt st...
